ROUND(3)		 BSD Library Functions Manual		      ROUND(3)

NAME
     round, lround, llround — round to integral value, regardless of rounding
     direction

SYNOPSIS
     #include <math.h>

     double
     round(double x);

     float
     roundf(float x);

     long int
     lround(double x);

     long int
     lroundf(float x);

     long long int
     llround(double x);

     long long int
     llroundf(float x);

DESCRIPTION
     The round() and roundf() functions return the integral value nearest to x
     rounding half-way cases away from zero, regardless of the current round‐
     ing direction.

     The lround() , lroundf() , llround() and llroundf() functions return the
     integral value nearest to x (rounding half-way cases away from zero,
     regardless of the current rounding direction) in the return formats spec‐
     ified.  If the rounded value is outside the range of the return type, the
     numeric result is unspecified and the "invalid" floating-point exception
     is raised. A range error may occur if the magnitude of x is too large.

SPECIAL VALUES
     round(�0) returns �0.

     round(�infinity) returns �infinity.

     The round() functions may, but are not required to, raise the "inexact"
     floating-point exception for non-integer numeric arguments.

     The lround() and llround() functions need not raise the "inexact" float‐
     ing-point exception for non-integer arguments that round to within the
     range of the return type.

STANDARDS
     The round() , roundf() , lround() , lroundf() , llround() , and
     llroundf() functions conform to ISO/IEC 9899:1999(E).
